Axel commented on LUCENENET-602:
--------------------------------
Hi Shad
I seem to have a slightly different error for what seems to be the same
underlying problem. Running the sample from Enrico works fine on Android and
the IOS emulators, but break runtime on a physical IOS device.

{code}
I found the cause of the problem to be the implementation of the LRUHashMap
using LurchTable. The LurchTable class is violating the restrictions in Mono
for IOS. I simply replaced the LurchTable with a randomly selected LruCache -
LruCacheNet https://www.nuget.org/packages/LruCacheNet/ and this solved the
problem.
Any chance you could fix this permanently?

> found the problem cause (I suppose...):
> _Value types as Dictionary Keys Using a value type as a Dictionary<TKey,
> TValue> key is problematic, as the default Dictionary constructor attempts to
> use EqualityComparer<TKey>.Default. EqualityComparer<TKey>.Default, in turn,
> attempts to use Reflection to instantiate a new type which implements the
> IEqualityComparer<TKey> interface. This works for reference types (as the
> reflection+create a new type step is skipped), but for value types it crashes
> and burns rather quickly once you attempt to use it on the device.
> Workaround: Manually implement the IEqualityComparer<TKey> interface in a new
> type and provide an instance of that type to the Dictionary<TKey, TValue>
> (IEqualityComparer<TKey>) constructor._
> So, what can I do? Thank you in advance, Enrico Caltran +393357485560
